I believe the explanation is that the _infile_ variable/buffer is a text structure, so it automatically converts the assigned value to character if it can. Maybe someone else can point you to proper documentation to that effect. I guess I was surprised that the assignment took place without an error or warning or at least a note that a conversion took place. I thought maybe it was just a special feature of _infile_, but then I tried this
length y $3;
y = 100;
Again, the assignment occurred without an error, warning or note.
